Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed May 6,1904. Serial No. 206,637.

To all whom it may concern.- Be it known that we, CHRISTOPHER Y. Mc-CARDLE, a resident of Cameron, county of Marshall, and SILAs N. DAVIS, aresident of Elm Grove, county of Ohio, State of West Virginia, citizensof the United States of America, have invented certain new and usefulImprovements in Ohurning Apparatus, of which the following is aspecification.

Our invention relates to new and useful improvements in churns, and moreparticularly to a churning apparatus; and it consists in the particularconstruction, arrangement,

and combination of parts, which will hereinafter be fully described.

The object of our invention is to provide a simple and durable apparatusor machine for churning which on account of the speed at which it can bedriven and because of the double or duplex movement of the dashersfacilitates and at the same time lessens the labor of churning.

In describing the invention in detail reference is herein had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a perspective view of the invention. Fig. 2 is a top planview of the same, showing the movable horizontal sections and braceswung outward; and Fig. 3 is a front elevation of a broken section ofthe invention.

Referring to said drawings, in which like reference-numerals designatelike parts throughout the several views, 1 indicates a base on which ismounted a churn-body 2. On said base at each side of the space occupiedby said churn-body 2 is an upright support 3. J ournaled in saidsupports is a shaft 4, having two oppositely-disposed cranks 5 therein,and on one end of said shaft is a small gear-wheel 6, which meshes witha large gear-wheel 7, mounted to be rotated by a hand-crank 8, which issupported in any suitable manner, a post 9, mounted on the base 1, beingillustrated in the drawings. Having their upper ends attached to saidcranks 5 are two toggle-arms 10. The lower end of one of said arms ispivoted to the upper end of a vertical rod 11, and the lower end of theother arm is pivoted to the upper end of a second vertical rod 12. Saidrod 11 is shorter in length than the rod 12 and carries upon its lowerend a dasher 13, while the rod 12 car ries upon its lower end a dasher14. Said rods, with their dashers, stand suspended Within the churn-body2, as shown, with the dasher 13 preferably directly over the dasher 14.Said rods are secured to said dashers at points outside the centerthereof, and the dasher 13 travels up and down on the rod 12, an openingor passage being provided in said dasher, through which said rod passes.One or more horizontal cross plates or braces 15 are secured at theirends to said supports and serve as braces for said supports and for therods 11 and 12. Semicircular recesses 16 are provided in the front edgesof said braces 15, in which said rods 11 and 12 partially lie.Horizontal sections 17, hinged or pivoted at one end on one of thesupports 3 and having their rear edges shaped to correspond with thefront edges of said braces 15 and also provided with recesses 18 forengaging said rods 11 and 12, are provided to fit against said braces 15to embrace and hold said rods in vertical position. The lower of saidbraces 15 is preferably located at a point just above the top of thechurn-body 2 and has therein set-screws 19, which are adapted to bemanipulated to cause their points to impinge upon, and thus firmly hold,the lid 20 of the churn in place upon the body 2.

A fixed brace 21 is provided on the base 1 at the rear side of thechurn-body, and a movable brace 22, pivoted at 23, is adapted to holdthe churn-body firmly in place while the machine is in operation. Apivoted hook 24 holds the free end of the brace 22 in place, while hooks25 are provided for holding the sections 17.

In operation the turning of the hand-crank 8 revolves the shaft 4, andconsequently the toggle-arms attached to the cranks 5 raise and lowersaid rods 11 and 12 alternately, producing what may be termed a doubleor duplex movement or stroke of the dash ers, they moving toward andaway from each other alternately.

To remove the churn-body from the machine, the movable brace 22 and thesections 17 are swung outward, the pins or pivots 26, which secure thetoggle-arms to the rods 11 and 12, are removed, and the set-screws 19are released, when the churn-body and the rods and dashers are entirelydisengaged from the machine and may be removed together.

As is obvious, any kind of motive power desired may be employed foroperating the machine. A pulley-wheel may be mounted on the end 27 ofthe shaft 4, so as to admit of the driving of the machine by belt.Instead of gear-wheels, shown in the drawings, sprooket-wheels and achain may be employed, if desired.

We have described our invention more or less in detail; but it isobvious that various slight changes may be made in the construction andarrangement of some of the parts composing the invention withoutdeparting from the general spirit or scope thereof. Hence we do not wishto limit ourselves to the precise construction and arrangement hereinshown and described.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

In a device of the character described, the combination with achurn-body, of a frame, a shaft with oppositely-disposed cranks thereonmounted in said frame over the churnbody, links connected with saidcranks, rods carrying dashers depending from said links within thechurn-body, pivots connecting said rods with said links, said pivotsbeing adapted for removal to admit of said churnbody and said rods beingtogether removed from the frame, pivoted braces having semicircularrecesses therein embracing said rods and holding them in verticalalinement, the lower of said braces located directly above thechurn-body, set-screws extending vertically through the last-mentionedbrace for impinging directly upon the churn-lid to hold it in place uponthe churn-body, and gearing for driving said shaft, substantially asdescribed.
